Specification

What you are actually getting

Where it runs
Your browser
Every tool is JavaScript running on your own machine. There is no upload step because there is no server to upload to.
What it costs
Nothing
No account, no usage cap, no watermark on the way out, no page that asks for a card once the work is done.
Without a network
Still works
Once a tool has loaded it keeps working offline. Useful on a plane, on hotel wifi, or on a train through a tunnel.
How long it takes
No queue
Nothing waits in line behind other people. The only limit is how fast your own device can do the work.

Asked often

Frequently asked questions

Short answers. If something is still unclear, send a note.

01Are all PDFHarbor tools really free?

Yes. Every tool on PDFHarbor is free with no usage limits, no watermarks, and no premium tier. You will not be asked to pay for anything or sign up to download your result.

02Do I need to create an account?

No. There is no sign up, no login, and no email collection. Open the tool, drop your file, and download the result.

03Are my files uploaded to your servers?

No. PDFHarbor tools process files entirely in your browser using local JavaScript. Your documents never leave your device, which is why the tools work even when you go offline after the page loads.

04Which PDF tools does PDFHarbor offer?

Fifteen tools covering the most common PDF tasks: Merge PDF, Split PDF, Edit PDF Pages, Rotate PDF, Watermark PDF, Page Numbers, PDF to Word, Word to PDF, Image to PDF, PDF to JPG, Compress Image, Protect PDF, Unlock PDF, Basic OCR, and PDF Metadata cleaner.

05Does it work on mobile?

Yes. Every tool works in any modern mobile browser on Android and iOS. Some operations on very large files may be slower on older phones, but functionally everything works.

06Is there a file size limit?

No hard limit. The practical limit is your device memory. Files under 100 MB work smoothly on most laptops and phones. Larger files may slow your browser but still process.

07What is the strongest encryption for Protect PDF?

PDFHarbor uses RC4 128 bit encryption, supported by all major PDF readers including Adobe Reader, Chrome, Edge, and Preview on Mac. It is suitable for everyday document confidentiality.

08Does OCR work on handwriting?

Basic OCR works well on clearly printed text in all major languages. Accuracy on handwriting is much lower (typically 30 to 60 percent) and is not the intended use case.
